My daughter can feed from both boobs for about 15 to 20 minutes a piece and she will pull away herself each time and I can hear her gulping down milk but she still acts like she is starving afterwards. Has this happened to anyone else? I mean, I know she gets a lot because she has plenty of wet and poopy diapers for a breastfed baby but she still acts hungry and I dont wanna have to supplement with formula very often but I dont know what else to do..
